DAMPER.

SPECIFICATION forming part of Letters Patent No. 305,373, datedSeptember 16, 1884. Application filed March 18, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, MARK S. BURROUGH, a citizen of the United States,residing at Merchantville, in the county of Camden and State of NewJersey, have invented certain new and useful Improvements in Dampers forHeating-Drums and Stoves, of which the following is a specification,reference being had therein to the accompanying drawings,- where- IO m-Figure 1 is a sectional view of my improved damper applied to aheating-drum. Fig. 2 1s a perspective view of the damper. Figs. 3 and 4are respectively a broken plan and transverse vertical section of thesame, and

Fig. 5 is a perspective of a modification.

My invention has relation to that form of heating-drum or stove damperswhich are provided with tortuous channels or fines for retarding thepassage of the hot gases from the fire-box, in order to utilize as muchof their caloric as possible for heating purposes; and it has for itsobject to provide a simply-constructed damper which will have acircuitous passage-way or flue so arranged that the hot gases are notonly retarded, but are also projected against the sides of the drum,stove, or pipe, to more fully obtain the benefit of their caloric forheating purposes, and thereby cf feet an increased saving in the fuelrequired for heating purposes.

My invention accordingly consists of a heating-drum, stove, or otherlike damper comprising a fixed or rotating disk having a cen- 3 5 tralaperture and a diametrical or radial passage or fine on each side ofsaid dlsk, each of which communicates with its central opening, and arearranged at right angles to one another, or have different courses ordirections,

0 as hereinafter more specifically described and claimed.

In the drawings, A represents a heating drum or pipe of any suitable orusual construction to suit the stove or heater to which 5 it is designedto be applied. The moutha of its outlet-pipe a may, if desired, beprovided.

with a dam or plate, M, for preventing the too ready escape of the gasesof combustion after finding their exit through the dampers B, Any numberof the latter may be used, the

number depending upon the size and construction of the drums and thedegree and extent of heating requirements demanded. These dampers may befixed or rotating, as desired.

I prefer to provide them with the usual or other axis or shaft, b, andhandle I), for rotating them, in order that the draft for the firebox orthe escape of the hot gases therefrom may be regulated as desired. Thedampers are provided with the customary slots or depressions, b, for thepassage of the axis or shaft b,- or the latter may be secured to theformer in any other suitable manner. Each damper is composed of a diskor plate, 0, having a central opening, a, and on each side or on itsupper and lower surfaces, 0 0 is aflue or channel, D D, respectively.These flues communicate with the central opening, 0, and are showndiametrically or radially arranged at right angles to one another,withtheir ends (l nearly flush with the edge of the disk or plate 0.

Instead of using a single flue or channel, D, on each side of disk 0,two or more radiallyarranged flues may be used, as indicated in Fig. 5,and the plate 0 may be oblong in outline or otherwise configured, asdesired, the result whereof is, that as the ends of flucs D D are theonly openings for the hot gases to find their way into or emergetherefrom in order to gain a passage through the dampers, it followsthat such gases will always strike the sides of the drums as they enterthe lower flues, D, and as they lave or find their exit out of the upperflues, D, of the damper. The repeated impact of the gases against thesides of the drum heats the latter or causes said gases to impart theircaloric to the drum for radiation into the apartment to be heated.

What I claim is-'- 1. A drum or pipe provided with one or 0 more damperscomposed of a plate, 0, having an opening, 0, and fines D D on each sideof said plate, and arranged at right angles to one another,substantially as shown and described.

2. The damper B, composed of plate C,with 5 opening 0 and diametricalor. radial flues D D on opposite sides of said plate, and arranged atright angles to one another, substantially as shown and described.

3. The damper B, composed of plate C, hav- I00 ing opening 0 and fines DD on opposite sides of said plate, and having different directions,

and communicating with said opening, sub- In testimony whereof I affixmy signature in presence of two witnesses.

stantially as shown and described. MARK BURROUGH' Witnesses:
